Fold 1/2 cup black beans, 1 tablespoon salsa, and 1 slice cheddar cheese in a small flour tortilla. Cook in a dry nonstick pan until the cheese is melted and tortilla is lightly browned. Then wrap it in foil and stick in a plastic baggie for easy transport.
The colon (large intestine) is a distal part of the gastrointestinal tract, extending from the cecum to the anal canal. It receives digested food from the small intestine, from which it absorbs water and ions to form faeces. Anatomically, the colon can be divided into four parts â ascending, transverse, descending and sigmoid. These sections form an arch, which encircles the small intestine.
Mapping the body: the sigmoid colon. The sigmoid colon is towards the bottom right of the large intestine. It is usually patients not doctors who balk at the sight of a medical instrument being unwrapped. But the flatus tube, used to treat a condition of the sigmoid colon, is one no surgeon relishes. The sigmoid is an S-shaped stretch of large bowel, about 40cm long, which leads up to the rectum.
